The Snyder Industries Septic Cistern Riser 12 (MPN SII-5160000W94201) is a residential and light-commercial septic vessel built for direct-bury service, with structural rib reinforcement rated for typical residential burial depths under standard backfill conditions.
Design
- Internal baffle (one-compartment) or compartment-divider wall (two-compartment) integrally molded — no field assembly
- Manway risers and lid accessories sized to the OEM connection — specify when ordering
- Direct-bury rating — rib-reinforced wall handles typical residential backfill loading at code burial depths
- Lightweight enough for one-truck set: typical 1000-gal HDPE septic tank weighs under 300 lb empty vs. 7,000+ lb for equivalent concrete
- Manufactured to IAPMO IGC 247 (where labeled certified) for residential single-family on-site sewage treatment
Installation
Install per the local on-site sewage treatment code (typically a state-level adoption of IAPMO Uniform Plumbing Code Chapter 7 or the International Private Sewage Disposal Code). Bury depth, backfill material, inlet/outlet invert elevations, leach-field sizing, and required permits are jurisdiction-specific — verify with the local health department before excavation. Lay the tank on a level sand or pea-gravel bedding course; backfill with the same material to prevent point-loading on the rotomolded shell.
Common applications
- Replacement for failed steel or concrete legacy septic tanks
- Job-site temporary construction-worker sewage holding before connection to municipal sewer
- Agricultural-property worker-housing septic system primary tank
- Remote-research-station and field-camp on-site sewage treatment
- Single-family residential septic primary treatment tank
- Cabin, lake-house, and weekend-property on-site sewage treatment
Compatibility & compliance
Where carrying the IAPMO IGC 247 certification mark, the tank is approved for residential single-family on-site sewage treatment systems under jurisdictions adopting the Uniform Plumbing Code or International Private Sewage Disposal Code. State-level approvals (Florida, Massachusetts, California, others) are jurisdiction-specific — verify the model's approval status with the local health department before purchase.
